BORDAU 1: stn DW 1465, 18°09’S , 178°39’W , 290-300 m , 1 dd (Fig. 6I) . — MUSORSTOM 10: stn stn CP 1363, 18°12’S , 178°33’E , 144-150 m , 3 dd; stn DW 1384, 18°19’S , 178°06’E , 260-305 m , 1 dd. DISTRIBUTION. — Southern Japan (in 50-200 m ; Tsuchiya 2000) and Fiji (new record), depth of living specimens unknown, shells in 150-290 m . REMARKS. — Monstrotyphis imperialis Keen & Campbell, 1964 has been dredged off New Caledonia , but to date, no specimens of the similar M. montforti have been recorded from that region. Monstrotyphis montforti differs from M. imperialis in having anal tubes forming an angle of 40-47° with the axis of the shell (rather than 70-85° in M. imperialis ), and in having a smooth siphonal canal rather than an ornamented canal with a broad, fluted spine in M. imperialis ).
